13. VEGETATIVE PROPAGATION OF Cordia trichotoma (VELL.) ARRAB. EX STEUD. BY CUTTINGS FROM SHOOTS AND ROOTS
ABSTRACT Cordia (Cordia trichotoma (Vell.) Arrab. ex Steud.) is a native species that has high quality wood and potential for the establishment of commercial plantations. However, its propagation by seeds is difficult, and vegetative propagation is a good alternative. The aim of this study was to evaluate the vegetative propagation of cordia by cuttings from

14. GERMINATION POTENTIAL AND VEGETATIVE PROPAGATION OF Aegiphila brachiata VELL
ABSTRACT The objective of this study was to evaluate the germination potential of Aegiphila brachiata (peloteiro) and its propagation through stem-cuttings, as well as how the age of parental plants and the application indolebutyric acid (IBA) and inoculant of Azospirillum brasilense influence adventitious rooting of the species. Thus, the physical character

15. CONTROLLED RELEASE FERTILIZER IN THE ROOTING AND PERFORMANCE OF CLONES OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native forest species of great economic and ecological interest, currently at risk of extinction. In addition to the difficulty of finding adult individuals of this species, plant production is limited, so the use of mini-cuttings can facilitate the spread of P. peroba. Thus, the objective of this study was to analyse the effe

16. Budbreak induction in kiwifruit vines cultivated in an organic system by the biological method of single node cutting
ABSTRACT Kiwifruit vines are an alternative approach to diversify Brazilian fruit farming because of the low supply and increase in the demand for their fruits. Hydrogenated cyanamide, which is the most common rest-breaking agent, is highly toxic and its use is not allowed in organic production systems. This study aimed at evaluating the efficiency of altern

17. Fertility of buds and pruning recommendation of different grapevine varieties grown in altitude regions of Santa Catarina State, Brazil
ABSTRACT Low bud fertility index is frequently observed in different grapevine varieties grown in high altitude of Santa Catarina Sate; in many cases less than one cluster per bud is observed. The objective of this study was to assess bud fertility of twenty six Vitis vinifera L. varieties and from this information, to recommend the method of pruning more s

18. MINI-CUTTING TECHNIQUE FOR VEGETATIVE PROPAGATION OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagati

19. Peroxidase activity and initial growth of ‘Barbosa’ peach on clonal rootstocks
Resumo Na produção de mudas de pessegueiro é frequente o uso de porta-enxertos de identidade genética desconhecida, obtidos a partir de caroços nas indústrias de conservas. A hipótese testada foi de que existem porta-enxertos que expressam maior compatibilidade, possibilitando maior sobrevivência e melhor crescimento, e que a atividade da peroxidase

20. Exigência nutricional e produtividade em minijardim clonal de Toona ciliata var. australis
Resumo O estado nutricional da planta-matriz é imprescindível para a manutenção do seu vigor vegetativo, fundamental para a produção de miniestacas. Portanto, o fornecimento de nutrientes em quantidades ideais durante o manejo das minicepas influencia o sucesso da propagação. Objetivou-se com este estudo avaliar e comparar a produtividade do minijard

21. Phenological behavior and agronomic potential of blackberry and hybrids in a subtropical region
ABSTRACT The purpose of this study was to evaluate the phenological behavior and agronomic potential of blackberry varieties and hybrids in a subtropical region. Blackberry seedlings of four varieties and two hybrids were purchased in April 2015 in the form of stem cuttings and transplanting in July 2015. Winter pruning was carried out on August 18, 2016 and

22. Glyphosate as Growth Regulator for Bahiagrass and Broadleaf Carpetgrass
RESUMO: Objetivou-se neste trabalho avaliar o efeito do uso do herbicida glyphosate como regulador de crescimento em grama Batatais e São Carlos. Os experimentos foram conduzidos em casa de vegetação no delineamento inteiramente casualizado com dez doses de glyphosate: 0; 5,625; 11,25; 22,5; 45; 90; 180; 360; 720; e 1.440 g a.e. ha-1 e quatro repetições

24. Comparison of Volatile Profile and Antioxidant Activity of Piper divaricatum G. Meyer (Piperaceae) Using Cuttings and Cell Tissue
In this study, P. divaricatum (Piperaceae) plants were subcultured by cuttings and cell tissue in order to carry out a comparison of the volatile profile, phenolic compounds, and antioxidant activity. Propagation by cuttings used vermiculite substrate and Murashige-Skoog (MS) medium in the absence of growth regulators and rooting started at 15 days of growth
